In batteries, the cut-off (final) voltage is the prescribed lower-limit voltage at which battery discharge is considered complete. The cut-off voltage is usually chosen so that the maximum useful capacity of the battery is achieved. The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When testing the capacity of a NiMH or NiCd battery a cut-off voltage of 1.0 V per cell is n… Web18650 lithium-ion batteries are charged up to 4.2V and down to between 2V and 3V depending on the cell's specification for cut-off voltage. ... The BMS will shut the entire pack down as soon as one battery discharges to the low voltage point. Lithium batteries do not, or should not, be discharged to 0 volts, ever.
